SPECIFIGATION forming part of Letters Patent No. 617,338, dated January 10, 1899.

Application filed July 28,1898. Serial No. 687,151. (No model.)

To all whom it may concern:

Be it known that I,' EDWARD M. HEYLMAN, of Canton, in the county of Fulton and State of Illinois, have invented certain new and usef n l Improvements in Riding-Flows, of which the following is a specification.

The improvements are embodied in means for raising and lowering the plow in the carrying frame, in means for adjusting the tonguecontrolled wheel, in means for 'controlli'n g the rear caster-wheel, in bearings for the bails on which the plow-beam is swung, and in means I forregulati-ng the pitch of the plow. It is exemplified in the structure hereinafter de scribed and it is defined. in the appended claims. I I In the drawings forming part of this specification, Figure l is a plan of so much of a plow as is needed to describe my improvements. Fig. 2 is a side elevation of the structure shown in Fig. 1. Fig. 3 is a side eleva-' I tion of the mechanism employed to raise and 7 lower the tongue-controlled wheel. Fig. 4 is an elevation of the opposite side of the mechanism shown in Fig. 3. Fig. 5 is a side elevation of a bracket and boxing used to provide for varying the pitch of the plow and improving the connection between the plowbeam and the front bail. Fig. 6 is a plan of the bracket and boxing. Fig. 7 is a side elevhtion illustrative of the operation of the plow raising and lowering mechanism. Fig.

8 is a detail of the plow raising and lowering mechanism. Fig. 9 is'a side elevation of the means used to control the rear caster-wheel. Fig. 10 is a rear elevation of the mechanism shown in Fig. 9.

In this instance the frame of the plow is made of a metal bar bent to form a rectangle, ,as shown at 1. A carrying-wheel 2 is connected with one side of the frame, near the center thereof, a tongue-controlled wheel 3 is connected with the front end of the frame on the side opposite wheel 2, and a caster-wheel 4 is connecte'd'with the rear end of the frame.

, Downward-extending brackets 38 are fastened to the front portion of the frame on opposite sides thereof, and .an upward and forward extended bail 7 is pivoted at its ends in the brackets 38. Upward and forward extending bail 13 is pivoted at its ends 'in down- Ward-extending brackets 37, which are fastened to the rear (rid of the frame, and the beam 5 of the plow 6 isswung from the bails in a manner to be hereinafter set forth. The bails connect the plow-beam with the frame in a manner to'permit rise and fall of the plow with relation to the frame, and the means by which the raising and lowering is effected constitutes one feature of the invention. To construct this feature, I provide a pivot-bearing, as 18, on a side of the frame and extend a pivot-pin through it. On one end of the pivot-pin I fix a handle 17. On the.other end I fix a crank-arm 19, and I connect the crankarm with a bracket 16 on the plow-beam by means of a downward-extending link 25. The crank-arm 19 extends upward and forward when the plow is raised, and it has an extension 20, turning downward and forward at an abrupt angle with the body of the arm.

A bell-crank lever 22 is pivoted to the frame in front of the pivot of arm 19. One of itsv members, 23, extends rearward and its other member, 24, extends upward and is turned sidewise to form a foot-bearing. A link 21 connects member 23 of the bell-crank lever with extension 20 of the crank-arm in such manner that when the plow is raised the pivot of the bell-crank lever and the two connec- 8o tions of link 21 fall on a right line, or approximately so, and form a dead-center lock 'to hold the plow raised. .When the plow is raised, the handle 17 extends backward, the

crank-arm extends upward and forward, the

member 23 of bell-crank lever 22 extends toward the swinging end of the crank-arm, and the foot-bearing member 24 of the bellcrank lever extends upward and rearward.

This condition, is illustrated in Figs. 2 and 8, e

ter which the plow will fall of its own weight,

forcing the foot-lever to the position shown in dotted linesin Fig. 7 and then carrying it back to its original position, as shown in solid lines in the same figure. The are described by the pivot of link Ell-with member 2'0 of the crank-armis half above and half below a right line drawn from the pivot of the crankarm to the normal position of the pivot of the link with the foot-lever, and so the foot-lever is carried from its normal or rearward position as the crank-arm rises or falls and assumes'the same position when the-plow is entirely lowered that it maintains when it is entirely raised. At the half-throw of the crank-arm in either direction the foot-lever is carried back to the position shown in dotted lines in Fig. 7, and at the termination of a full throw up or down the foot-lever assumes the position shown in solid lines in Figs. 2, 7, and 8. This peculiarity of construction gives the foot-lever utility as a lifter, as well as a lock, and when the plow is to be raised the operator has a choice of modes of procedure. He may grasp lever 17 with his hand and draw it backward in the customary manner, he may use the hand-lever and the footlever conjointly, or he may give the foot-lever quick pressure and release and raise the plow without touching the hand-lever. The operation last described is made feasible by the introduction of a balancingspring 15, which exerts upward stress on the plow to an extent to nearly equal the plows weight, and so when upward motion is given to the plow by for: ward pressure on the foot-lever the momentum ,so developed, aided by the tension of the spring, carries the plow to its highest position, where it is automatically locked by the raising mechanism. It is to. facilitate the plow-raising action of the foot-lever, whilev giving the link'25 sufficient rise, that the extension 20 of arm 19 is turned downward from the pivot 25 of the link. This gives the link increased upward pull on the crankarm in act of raising the plow, as it. throws the pivot of the link, with the crank-arm, downward below the pivot of the crank-arm. It is desirable that the foot-lever shall have a stop to limit its forward throw, and such provision is made in this instance by extending a portion 21 of link21 beyond the pivot of the link with the foot-lever and forming a stop projection on the foot-lever in position to engage the extension when the plow is raised.

The plow is swung from the bails by means of brackets 8 and 14, which are preferably made each of two parts adapted to fit against opposite sides of the plow-beam, and the brackets have pivot-bearings particularly adapted to economize material and judiciously utilize the strength thereof. The details of the bearings are shown in Figs. 5 and 6. The lower half of the bearing is formed in the bracket, clamp extensions 8 extend upward in front and behind the bearing and project toward each other at their upper ends,

a bearing-block is held between the extensions 8, forming the upper half of the bearing, and abolt l1 binds the clamp extensions form angles with the extensions approximating forty-five degrees, and the block has corresponding angles, so that when the extensions are clamped onto the blqck the block is forced downward by inclined-plane action in. close contact with the lower half of the hearing and the bail therein. A pair of bearings having the described peculiarities is provided for each bail, and the resultsattained are that the bail may be readily detached from. the brackets. The stress of the ball is on the bearing itself, and the securing-bolt is applied in a manner to accomplish the double eifect of holding the block against lateral movement and clamping it against the other half of the hearing. I

The downward swing of the front bail is limited by stop-arms 12, and the swing of the so that its bearings may be swung backward or forward as ofccasion demands. The pivot is located at 8 below the bearing, and a rearward extension. has a slot 8 concentric with the pivot-bolt. The surface adjacent to the slot is preferably corrugated or roughened, and a bolt extends through the slot and pro vides means for binding the'rcarward'extem.

sion of the bracket firmly against the plowbeam. The pivot-bolt engages the plowbeam, and the bearing of the bracket may bethrown forward or backward to increase or diminish the vertical movement of the plow by loosening the bolts, swinging'the bracket on thejpivot-bolt, and retightening the bolts.

The tongue-controlled wheel 3 requires to be raised and lowered with relation to .the plow-frame in drder to meet diifering conditions, and one feature of my invention is designed to provide simplified means for accomplishing this result, as follows: Ayertical sleeve 40 is fixed in a lateral extension 1 of the plow-frame, and it is provided with a rearward extending arc-formed rack 41.

The vertical portion of shaft 39of wheel 3,

extends through the sleeve and journals therein. Acap 44 is fixed onto the upper end of the shaft and provided with a laterallycxtending shaft. vzitbracket 46 is journaled on shaft 45, and the tongue 47 is fastened to the bracket. Immediately below cap 44 a The greater the dis-- 55 sleeve.

6 rest.

5 A lever 48 is fulcrumed below the frame at' l9 on sleeve 40 and extended obliquely rearward to the part of the plow on which the 7 driver sits. The lever is deflected downward near its fulcrum, as shown at 48 inFig. 4,

to and from the lowest portion of the bend a rod 54 extendsupward and engages'collar l2. A casting 50 on lever 48 forms a housing for a lock-bolt 51, which engages the toothed rack 41, and the housing, is so constructed that the bolt moves toward and from the fulcrum of the lever in engaging and disengaging the teeth. The bolt is spring-actuated in one direction, and a grip-lever 53 and connecting-rod 52 provide means for moving the bolt in the contrarydirection'. The downward deflection of the lever enables the connection of rod 54 with the lever to swing equal distances above and below a line drawn from the fulcrum at right angles with the sleeve, thus economizing the force applied to raising or lowering the wheel, and it also provides clearance to avoid the frame extension, asgshown in v Fig. 4. construction of the housing 50 with relation to the deflected lever gives the lock-bolt proper mechanical action, and the result of the entire contrivance is to provide for raising and lowering, the wheel by direct action of a single lever. The driver sitting in 3 5 position may grasp the lever 48 and carry it from its lowest position (shown in Fig. 3)- to its highest position (shown'in'Fig. 4) without any inconvenience, and the wheel will be correspondingly shifted by force applied to 0 the collar; 42 through rod 54.

pressure in turning around, and provision should be made to hold it entirely rigid in backing and possibly in other unusual circumstances. To provide for these different requirements, I extend the vertical portion of shaft 26 of the caster-wheel through and above the bearing-sleeve 28, which is fixed to the plow-frame, put a nut 36 on the upper end of the shaft, and place a spring 35 be tweenfthe nut and the upper end of the On the lower end of the sleeve I form a downward extension having beveled edges, and on the shaft immediately below the sleeve I fixacollar 29, which has a recess to fit the extension on the sleeve when the wheel is in operative position.

On alu g extending rearward from the sleeve I pivot a lock-lever 27, and in the rear side of collar 29 Iform a square notch 30 in Fig, 10, in which the lower end of the lever 27 may beyond the lever on one side. A stop-collar The peculiar The pivot-bolt 32 of lever 27 extends 31 is placed on the bolt and against the le-' ver, and a spring 33 is made to press the collar against the leverand hold it in any position in which it may be swung. To aid the spring, the collar has a recess qr recesses to receive a beveled rib 34 on the lever.

Thespring 35 tends to hold the inclined extension of thesleeve in the recess of collar 29, thereby keeping the wheel yieldingly in operative position, andwhen it is desired to make the wheel unyielding in its operative position the lever on the sleeve is made to engage the notch in collar 29. \Vhen the lever 27 is swung out of contact with collar 29, the caster-wheel shaft may swing under extreme stress, and'in whatever position the 1ever is placed the spring 33 and the collar 31 will hold it against unintendedmotion.
